Message-ID: <CrDswJ.7qE@cti-software.nl> Organization: CTI Software BV, The Hague, The Netherlands Date: Tue, 14 Jun 1994 09:55:29 GMT Lines: 50 After the Adaptec AHA-1742 EISA SCSI host adapter went out of production, I tried my luck with a couple of BusLogic 747S cards. They were to run with ISC Unix 4.0. At that time, the AHA-2742 driver was not there yet. Although the cards seemed to work fine, the machine would lock up when multiple SCSI drives are accessed simultaneously. This could happen when accessing both tape and disk simultaneously, but would almost happen immediately when accessing two disks. When that happens, all processes seem to keep running, until they access the disk. I have tried all sorts of hardware. Different disks (old SCSI-1's and all sorts of new ones), different tape drives (Exabyte 8mm, HP DAT, Sankyo QIC-150), different systems (Intel 403E, Intel XPRESS) with no difference. I had three BusLogic cards to test. At the time, I was unable to test any other OS than ISC. I have tried to disable sync negotiation, EISA burst cycles, and FAST SCSI with no difference. I used native mode (using the ISC "bl" driver), and Adaptec compatibility mode (using the "aha1540" driver) with no difference. Replacing the BusLogic with an Adaptec (1542 or 1742) would *always* fix the problem. The problem is that our BusLogic dealer says "the cards work just fine with SCO and Netware, it must be your ISC driver" and our ISC dealer claims I've got a hardware problem, as the card fails with two different ISC drivers. To help me out of this situation, I would like to know of anyone using the 747S with multiple drives 1) Which OS are you running 2) Are you using native or aha1540 drivers 3) What is the firmware revision of your card 4) What SCSI drives are you using 5) What kind of system/motherboard are you using The firmware on my cards is revision 1.37. Any other information leading to a solution to this problem would be welcome too.
